LiDAR, Local Relief Models and Sketchfab

Cranbrook Castle; LiDAR based Digital Terrain Model (DTM)

Cranbrook Castle; LiDAR based Digital Terrain Model (DTM)

The following visualisations were produced as part of the Fingle Woods and Castle Drogo Aerial Survey Analysis and Interpretation project, recently completed for the National Trust. There is a visualisation for each hillfort in the study area: Prestonbury Castle, Wooston Castle and Cranbrook Castle.

The visualisations were produced from a Digital Terrain Model (DTM) based on LiDAR data provided by Bluesky at 25cm resolution. This DTM was also used to produce a Local Relief Model using one of the ArcGIS tools currently being developed by Archaeogeomancy for the National Trust. The LRM was then draped over the DTM, exported as VRML and uploaded to Sketchfab. Continue reading

Android Storage: SDHC and SDXC

Storage by Dominik Bartsch

Ever wondered why there is a 32gb limit on storage cards on many Android devices? If you, like me, have a lot of data you want on your mobile device (business docs, music and map data in my case) and found this a bit restrictive, you’ll be pleased to know there is a workaround. Continue reading

Maplets – static images of maps for use in applications

Toolbox by Florian Richter

Toolbox by Florian Richter

For a while now, I’ve been using the Data Driven Pages functionality of ArcGIS to output static maps, indexed by feature, to include in database driven applications such as MS Access and/or dynamic websites including Content Management Systems. This is a neat way of providing contextual location information on forms and reports in Access or on webpages without having to deploy GIS.

TACOS: 21st Century Geospatial #HistEnv Data Management

TACOS – the event

On 14 May 2014 the Council for British Archaeology (CBA) hosted a one day seminar on behalf of FISH and HEIRNET at the University of York to discuss common issues facing the historic environment information sector and make progress towards a shared vision and agenda for historic environment information management.

The TACOS keynotes, discussions and demonstrations will build upon a ‘show and tell’ event (the NACHOS seminar) held at the British Museum in November 2012, which identified the need for integration of information sources in support of the National Heritage Protection Plan (NHPP). The seminar will investigate current historic environment information management practices and identify areas for improvement through cross-sector collaboration.

The key aims of the seminar were to:

  • Encourage discussion between different groups that produce and manage historic environment information from across the sector (professional, research and voluntary to identify common goals and issues
  • Develop information sharing networks and working partnerships across the sector to pool resources in the areas of skills development and application of information technology

There’s more info on the event (aims, topics, etc) here. Continue reading

Technology refresh; new smartphone

Phablets by Maria Elena

It became apparent by late 2013 that archaeogeomancy communication tools needed updating. Working on my PhD and commercial contracts from all over the place and having access to apps on the move became critical and, put simply, my Nokia E7 was struggling. A new smartphone was required.
